Helical Solutions 82247 Corner Radius End Mill 3/4in 6 Flute

Product Description

The HELICAL SOLUTIONS 82247 is a solid carbide corner radius end mill designed for high-performance material removal in demanding machining environments. Built to the HEV-C-6 series specification, it features a 3/4-inch diameter, a 0.0600-inch corner radius, and six flutes with variable index geometry for reduced harmonics and improved surface finish. The APLUS PVD coating enhances wear resistance and extends tool life when cutting ferrous and exotic materials. Licensed machinists and CNC programmers working in job shops, aerospace, and precision manufacturing install this tool in high-precision toolholders for roughing and semi-finishing operations.

This end mill is suited for single-end milling operations in ferrous metals including low-alloy steel, medium alloy steel, tool steel, and cast iron, as well as titanium and superalloys. It is also rated for secondary applications in stainless steel and non-ferrous metals. The centercutting design allows plunge entry, and the right-hand flute direction with right-hand cutting geometry is compatible with standard CNC vertical and horizontal machining centers. High-precision toolholders are recommended to maintain runout within the stated TIR maximum.

Key Features

• Variable index flute geometry reduces chatter and vibration during aggressive roughing passes
• APLUS PVD coating provides thermal and wear resistance for extended tool life in steel, cast iron, and titanium
• Centercutting design enables plunge milling and ramping without a pre-drilled pilot hole
• Solid carbide construction delivers rigidity and dimensional stability over long cut lengths
• 0.0600-inch corner radius reduces stress concentration at part edges and extends tool engagement
• Straight-cylindrical shank compatible with standard collet chucks and shrink-fit toolholders

Compatibility

Designed for use with high-precision toolholders. Primary workpiece materials include low-alloy steel, medium alloy steel, tool steel, cast iron, titanium, and superalloys. Secondary workpiece materials include stainless steel and non-ferrous metals. Part of the HELICAL SOLUTIONS HEV-C-6 series.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before tool changes. Seat the straight-cylindrical shank fully into the toolholder and torque the retention mechanism per the toolholder manufacturer specifications. Verify runout at the tool tip does not exceed the stated TIR maximum before beginning a production run.
